Q1 claim; (era- 19) U V The invention relates to apparatus forthepvalve. QTheair-admissiOn as wella s the exhaust treatment of naturaland artificial silks' and velvets, more particularly as'utilized inconnection with the usual boil-ofi operation o'r'dyeing' 5 operation towhich these materials are subjected.

It has for an object the provision of simple and efiective meanswhereby'the time required for these operations may be materiallyreduced, as a matter of fact to less than 'onehalij the timesnowrequired with-types of appa'ratus'in present use.

A further object of the invention resides in the provision of apparatusof this nature wherein the use of chain blocks and othermanuallyactuated means for positioningthe reels'of material, dropping the same"into the vats and removing them therefrom is eliminated, and whereinall of the operations may be conducted 'inuch greater by a singleoperative and with expedition andconvenience. a 7

Still another object of the invention resides in the provision ofapparatus whereby a pair of reels is simultaneously'treated in the vatsprovided therefor; and, when the desired operations are completed,whereby said reels may be quickly and readily raised out of the vats andswung into position forunloading and reloading." In carrying out theinventiorrprovision is made for suspending a pair of'reels, loaded-withthe goods tobe boiled-01f or dyed,"from the "ends liquid, but when-theseoperations are "completed and'when thereels havebeen withdrawn fromtheir respective vats, theymay be swung about thei'v'ertical axis of therod'to a position 101' unloading 'or removal from the'cross he'ad;

' When a new set of reels is to-be'treated, they are first suspendedfromthe opposite ends of V a this cross-head, which is then again swungabout into position to alignthe reels with the respective vats andintowhich they; are then lowered for reciprocation. .This operation ofreciprocat ing the reels while immersed in theiryats is arranged to bevaccomplished automatically in the provision of an air-drivenpistonforreciprocating the said rod carrying the cross-head. To this end, airis introducedbehind the' piston,

through a suitable valve, and an exhaust con-' nection is also madethereto through alfurther is arranged, not only for manual control; but

also for automatic operation from the movement the outflow of thefair sothat the piston will not" descend too rapidly. 1 a I l The nature of theinvention, however, will best: be understood when described inconnection with the accompanying drawings,v in which:

Figi'l is a front elevation, partly in vertical;

section; showing an installationof the novel" apparatus in associationwith a pair'of vats.

Fig. 2 is amore or less diagrammatic view] illustrating the action 'ofthe valve-operating. mechanism; and Fig. 3 is a fragmentary plan. of aportion thereof. f 1

Referring to the drawings.) I0 designatesa suitable pit or well intowhich. alportion oithei apparatus may be sunk to, reduce the height ofthe same above the surfaceor'grade |l.- Upon either side of this pitarealjso sunk two tanks orvats l2 and 13, respectively, only "a portion;however, of the same being'below-grade.

Within the pit'is mounted acylinderuifa'having the piston I6 mountedforureciprofcation thereinfthere being attached to the bottom or I thepiston aperforated metal bumperl-I adapt- 7 of said piston rod, orspindle. The said spindle v carries also at its extremeouter end andbeyond the'cross-head 22an electric motor 23,which,' is geared, by,means .of the meshinggcars 2 4,

withthesa id cross head .22. By energizing'the motor, as by closing thestarting switch 25 on panelZG; it will be appreciated that?thecrosshead-may be rotated about spindle 2G; and. reels 21' and 1 28suspended from its-opposite ends .maythus conveniently be brought. intoalignment with the vatsf-lZand. I3, into which} they are. to. beimmersed as "hereinafter set PATENT? O F E51? forth. Furthermore, whenthe treatment of the reels containing the goods is completed, the motormay again be operated to swing the crosshead into a position such thatthe reels carried thereby shall be substantially at right angles hadfrom a suitable source of air under pressure,;

as, for example, the tank 3i, Fig. 2, supplied from a motor-drivencompressori -32' and through suitable valves and piping hereinafter morefully set forth. From the connection 33,

an exhaust connection 33 is taken. witha'reducing valve 34 included tosuitably restrict the outflow when the piston is lowered undergravity-action so as to obviate an excessive rateof;

descent. I

. Suitable controls, both manual and automatic,

are provided for the'control of air from the said supply and exhaustconnections. ter connection 33 is provided with two manual,-

1y controlled valves 35 and 36, the valve 35' having an outlet 31directly to the atmosphere, while the outlet 38 from valve 36 connectswith an automatically controlled valve 39, Fig. 3, adaptedforexhaustinggas from behind the piston l5. pipe connection. '30, av supplyconnection 40 is had and in' the same is included a manually controlledvalve 4| for the supply of air underpressure to the cylinder and behindthe piston, said valve 41 being included in series with an automaticallycontrolled valve 42, Fig. 2, in the line from the supply tank 3|. Thesevarious .valves are preferably locatedon the panelifi;

and by manipulatingthe same as hereinafter? set forth, various controlsof the piston and at tached cross-head will be had for the'lloading,lowering and raising and'unloading of the reels.

The operation of the automatic valves 39 and 42 in order to. effect theautomatic operation of periodic reciprocation of the reels, is accomplished'from the reciprocation of piston rodf29.v

To this end, there is carried by. the rod,2or

rather its flange 2|, a tappet-rod 53 having adjustably secured thereonapair of tappets 5| and 52 which are separated from each other adistance corresponding to the length of' the reciprocation desired, itbeing understoodthat rod 50 will partake of the reciprocation of thepiston rod 20. These tappets are adapted to engage alternately with theforked end 53 of a lever secured to a rotatably mounted shaft 54.

The other end 55 of the lever ispivoted to spring toggle means embodyingthe oppositely acting spring-urged arms 56 and 51 and the This providesfor aspring-urged arm 58. spring-toggle control wherebyjwhen the arm 55is rocked past a horizontal position, it' will be snapped intoa'location at oneside or the other of the horizontal through the actionof spring-urged arm 58,'all of which is well understoodandforms noparticular part of the present invention.

The shaft 54', however, has mounted there-1 over a sleeve 60 providedwith a longitudinal slotGl into which extends a radially projecting pin'32 secured to the shaft; and fixedly secured to the said sleeveareoppositely extending valve operating arms-63 and 64, respectively.-These Thus, the lat- Beyond the exhaust connection to,

arms are adapted in one or the other of their positions, correspondingto the position of lever arm 55, to engage with or remain out ofengagement with respective valve stems 65 and 66, respectively, of thevalves 39 and 42, through corresponding laterally projecting fingers 6'!and 68 of the said arms. Thus, in one or the other of the set positions,the valve 39 will be opened for exhausting connection 38 directly to theatmosphere ,orbe shutoff; and, similarly, the valve 42 will be opened toadmit air under pressure behind the piston, or the supply of air be cutoff.

It will be understood that in the provision of islet Bland pin '52, alost-motion action is involved' so thatthe arms 63 and 64 will notimmediately follow the movement of arm 55 and Furthermore, provision ismade to insure a holding-inbf a valve during the period that aparticular cycle is taking place under its control.

vided at its ends with rollers 16, fl and 18, 19,

which are adapted {to embrace the respective fingers 6i and 68, one orthe other of a pair of rollers being inv engagement with a finger, inthe particular position to which it has been set, and serving thus toblock undesired movement of the corresponding arm.

When theperiod of automatic reciprocation has been completed through theautomatic operation hereinbefore described, and it is desired to unloadthe reel from the cross-head, the valve 4| may be manually operated toshut off the supply of air and the exhaust valve 35 may be similarlyopened to permit direct exhausting of the airfrom behind the piston.This will cause the cross-head to descend and with it the tappet52controlling-the exhaust. This tappet is then-loosened and-lowered tosuch an extent that in the subsequent elevation of'the crosshead noautomatic exhausting will result through action ofthe tappet. Bothexhaust valves 35 and 36 may then be shut off and the valve 4| againopened to admit air for elevating the cross-head sufficiently to swingthe reels 21 and 28 clear of the'tanks i2 and I3, whereupon, by closingswitch 25, the motor 23 may be operated for turning the cross-headsubstantially at rightangles to its previous position for unloading ofthe reelsand the loading on of a new set. The cross-head is thenvreturned to its position wherein the ends thereof are in alignment withthe tanks," and, lowered by closing of the valve:

4| and openingof exhaust valve 35. The tappet .52 is then again set forthe desired position, after which the air-supply valve, 4| is opened,-the exhaust valves '35 closed and the exhaust valve 36 opened, whichsets the apparatus for the. automatic. reciprocating cycle.
